In many religions, art and architecture have been used to concentrate spiritual energy or force in one spot. These “power points” might take the form of ephemeral chalked crosses on the ground as in Bakongo practice or monumental architecture as at Chichén Itzá. Often, however, they are precious objects and images crafted on a human scale and in permanent materials. Icons and reliquaries offer two examples of such “power points.” Both objects act simultaneously as loci of veneration and channels of communication between the pious and the divine.
